What is the best method of flashing code onto S32K148?

[Poley]

Hi all,

Sorry if this is a stupid question, I am used to using PIC's with PicKit so this is new to me.

I have been using the S32K148EVB and am now in the process of making a PCB with the S32K148 uC. I have a CAN bootloader that I flash onto the board and then use RAppID bootloader to flash the application code.

For the EVB I have been using OpenSDA in S32DS to program my .rbf bootloader file. I ideally don't want to have all of the OpenSDA stuff on the board so I was wondering what the easiest application would be for me to implement to flash my .rbf bootloader code to the onboard chip.

Thank you!

Hi @Poley,

The rbf file in s19 format can be flashed with any programmer (PE Micro Multilink, Segger J-link, Lauterbach, ...) via the JTAG/SWD port. (J10 on the EVB).

Daniel

Hi @danielmartynek 

Probably a stupid question but how do I get the .rbf into s19 format?

Thanks!

Hi @Poley,

Sorry for the confusion.

It is in S19 format and it can be loaded like this from the S32DS.

Instead of PE Micro OpenSDA you can use PE Micro Multilink.

Hi @danielmartynek 

That's perfect, thank you!

So as long as my design has the same JTAG pinout to the dev board (Will just copy it fully so it works the same):

Then I should be able to flash my .rbf using a JTAG tool in S32DS?

Thanks for the help!

Yes, that is correct,

I tested it with a PE Micro Multilink probe on S32K144 EVB.
